One of the most impressive underwater landscapes in the Canary Islands, the basaltic formation known as La Rapadura — Portuguese for brown sugar — emerges from the seafloor to within a few meters of the surface. These beautiful hexagonal columns are the result of molten lava that came in contact with the sea — as the magma cooled, the sloughed rock fractured in the form of a prism. Due to constant erosion over eons, some of these huge columns collapsed down to 160 feet deep, leaving at its base something that resembles a ruined city. Freediving is the purest way to enjoy this underwater landscape.
